D x= -9
Y=9
Because 4(-9)+45=9
I just put in each one and d got it right.
Pythagoras theorem, answer is sqrt69 or 8.307 to 3dp.
To find the inverse of a function, simply switch y with x:
So, y = 5x2 + 10 will become x = 5y2 + 10.
The correct option will therefore be A.
Area of each triangle
(1/2)(7)(13) = 45.5
Both triangles = 91cm^2
Area of rectangle = 4 * 13 = 52
52cm^2 + 91cm^2 = 143cm^2
The area of the parallelogram is 143cm^2
Answer:
x=5/2 or x=-4
Step-by-step explanation:
